BACKGROUND OF THE INVENTION

The present invention relates generally to providing medical implantsfor surgical use, and more particularly to providing one or more medicalimplants with associated holder mechanisms in a caddy where the medicalimplants and holder mechanisms are aligned in particular orientations inthe caddy.

There is a continuing need to provide medical implants for surgical usein a way that is convenient and organized for surgical staff. Inaddition, there is a need to track medical implants from their basematerials and manufacture through their use. Various regulatory bodiesthroughout the world have continued to impose stricter standards forsuch tracking. Tracking of non-sterile medical implants, i.e., medicalimplants that must be sterilized at the site of the surgery before eachpotential use, is challenging because traditionally such implants havebeen shipped in groups with other similar implants, but without specifictracking labeling. In recent years, many tracking packaging and labelingmechanisms have been developed which can be associated with each medicalimplant to be tracked and sold. However, many of these mechanisms havefailed to provide medical implants and associated packaging that bothallow for effective sterilization before each use and which also providefor convenient and organized presentation of the medical implants tosurgical staff. For example, many of these prior devices provide medicalimplants and associated packaging that may be placed anywhere in a trayor caddy, and/or the medical implants are placed in any orientationrelative to the tray or caddy regardless of the type or size of medicalimplant. Such mechanisms increase the risk that a medical implant willbe placed incorrectly in a tray or caddy of medical implants and usedinappropriately in surgery. To avoid such risks, medical staff mustspend extra time sorting, arranging, and managing surgical trays orcaddies used in association with such mechanisms. Alternatively, someindividual tracking solutions label each medical implant separately, butfail to organize and present the medical implants to the surgical staff.This solution requires a larger amount of operating room space toeffectively present the medical implants to surgical staff, and alsoincreases the risk of mistaken selection of medical implants by thesurgeon or surgical staff.

Improved mechanisms may provide a tray or caddy that is configured toreceive medical implants and associated mechanisms that provide for bothtracking and sterilization, and that present the medical implants in anorganized fashion relative to the tray or caddy. One or both oforientation and location of medical implants in a tray or caddy may becontrolled/arranged by size, shape, or other features via variousimproved mechanisms.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The following descriptions of the depicted embodiments are merelyexemplary in nature and are in no way intended to limit the invention orits application and uses.

One embodiment of a medical implant delivery system 1 is illustrated inFIGS. 1 and 2. In the illustrated embodiment, one or more medicalimplants 10 are coupled with respective holders 20. The implants 10 andholders 20 are shown as being supported in a caddy 30. In theillustrated embodiment, the medical implants 10 are configured as bonescrews. However, in other embodiments, the medical implants may beconfigured as any type of medical implant or instrument that isrecommended for sterilization prior to surgical use. Medical implants ofsome embodiments may not need to be sterilized, but may be moreeffectively organized or presented in the medical implant deliverysystem described herein. Non-limiting examples of medical implants ofsome embodiments may include other types of screws or fasteners and maybe treated or untreated with other substances. Possible treatmentsinclude combination or coating with materials such as hydroxyapatite orpolymers. Medical implants of some embodiments could be configured aswashers, plates, rods, nuts, special types of screws, linkages, staples,tethers, wires, intramedullary nails, external fixation devices, hipprostheses, knee prostheses, any instrument useful with any of thepreviously recited devices, or any other type of device that may be usedin a medical or surgical procedure.

An embodiment of the holder 20 is illustrated in more detail in FIGS. 3and 4. In the depicted embodiment, the holder 20 includes a top surface21 and a side surface 23 that is at least in part substantiallyperpendicular to the top surface 21. In FIGS. 3 and 4, a marking orindicia 24 is shown on the top surface 21 that provides basicidentifying information that corresponds to the medical implant 10. Forexample the number “24” of the marking 24 designates the medical implant10 as a screw having a 24 mm length. Markings or indicia on the topsurface of various embodiments of the holder 20 may relate to a lengthor another size parameter of any kind (i.e., height, width, diameter,etc.), or may present or abbreviate other information about anassociated medical implant.

In the illustrated embodiment, the side surface 23 includes identifyinginformation of greater detail by presentation of a detail marking orindicia 26. Information in the detail marking 26 may include, withoutlimitation, one or more of material lot numbers, implant sizes, types,configurations, manufacturing lot numbers, dates, locations, a uniqueidentification, or any other type of information or data relating to themedical implant 10 that is to be associated with a holder 20. Detailmarkings or indicia 26 may also include encoded data of any usable typeincluding, without limitation, visual, electronic, or magnetic data,such as but not limited to barcodes, QR codes, microchips, and magneticstrips. One example of a detail marking 26 of encoded data isillustrated in FIGS. 3 and 4 as the QR code of the coded marking 27.Coded markings may duplicate data included in the detailed markings 26,or may include any or all of additional data, electronic links, andother references. The illustrated detail markings 26 have a greatersurface area than the marking 24, as well as a greater number ofcharacters or features. In the illustrated embodiment, the ratio of thearea of the side surface 23 to the area of the top surface 21 is greaterthan three to one. However, various embodiments of the invention mayinclude marking to detail markings area and character ratios of otherproportions.

Markings or indicia on the top surface and the side surface may beapplied or created by any effective or suitable mechanism or technique.For example and without limitation, the markings may be milled, molded,etched, printed, cut, or burned into various embodiments of the holder.

The holder 20 illustrated in FIGS. 1-5 has a non-symmetrically shapedcross-section perpendicular to its longitudinal axis. The cross-sectionof the holder 20 is non-symmetrical about one primary axis in the planeof the cross-section. However, some embodiments may include holders thatare non-symmetrical about two primary axes in the plane of thecross-section. The cross-sectional shape of the illustrated holder 20 issubstantially similar to the cross-sectional shape of a skeleton key,with a planar portion parallel with the side surface 23 and acylindrical portion 28 (FIGS. 3 and 4) coupled along the planar portion.

The caddy 30 shown in FIGS. 1, 2 and 5 has a substantially planar topelement 31 with a top surface and a bottom surface and a number ofopenings 40 that extend through the substantially planar top element 31.A support structure 33 is coupled to the substantially planar topelement 31, as shown in FIGS. 1, 2 and 5. In the embodiment illustrated,the support structure 33 is coupled to the substantially planar topelement 31 on the bottom surface of the substantially planar top element31 to provide a volume adjacent to the bottom surface to allowcirculation of sterilization substances within the volume. Sterilizationsubstances may include steam or any other effective sterilizationsubstance such as but not limited to ethylene oxide. Combinations ofsterilization substances may also be used.

The openings 40 in the substantially planar top element 31 illustratedin FIGS. 1 and 5 have a non-symmetrical shape about at least one primaryaxis of the substantially planar top element 31. The primary axes of thesubstantially planar top element 31 in the illustrated embodiment areaxes that are parallel to the sides 38, 39 of the substantially planartop element 31. In an exemplary opening 40 shown in FIG. 5, the opening40 is non-symmetrically shaped about a primary axis parallel to the side39. The illustrated opening 40 is configured to receive a matchingnon-symmetrically shaped holder such as, for example, the holder 20 towhich the medical implant 10 is coupled. The holder 20 and implant 10are considered to match the opening 40 as the term “match” is usedherein. A “match” as used herein means an exact or a substantiallycommon shape or perimeter. Some embodiments may include one or moreopenings that are non-symmetrical about two primary axes in the plane ofthe openings. The shape of the illustrated opening 40 is substantiallysimilar to the shape of a skeleton key keyhole, with a substantiallyrectangular opening component 43 and an intersecting, adjacentsubstantially round opening component 48 (FIG. 5). In the illustratedembodiment, the substantially rectangular opening component 43 has oneside dimension that is less than the diameter of the substantially roundopening component 48. The term “diameter” used herein with reference tothe substantially round opening component 48 does not connote that thecomponent must be round, but refers to a largest extent or mean extentof the component. The substantially round opening component 48 isconfigured to receive the cylindrical portion 28, and the substantiallyrectangular opening component 43 is configured to receive the planarportion, which in the illustrated embodiment is parallel with the sidesurface 23. Other embodiments may include openings with other effectivenon-symmetrical shapes.

As illustrated in FIGS. 1, 2 and 5, when the holders 20 and medicalimplants 10 are received in the openings 40 through the substantiallyplanar top element 31 of the caddy 30, the holders 20 are aligned in apredetermined orientation relative to the substantially planar topelement 31. In particular, in this embodiment, the markings 24 of themultiple holders 20 are presented in readable orientations common withone another, and which are readable from the same orientation as thesize labeling on the substantially planar top element 31 when theholders 20 and the medical implants 10 are received in the openings 40.Although, for clarity, multiple openings 40 in the illustratedembodiment are shown without received holders 20 and medical implants10, in some embodiments, each of the openings 40 may be utilized.

Alternate embodiments of a caddy 130, 230, 330, 430 are illustrated inFIGS. 6-9, respectively. Each caddy 130, 230, 330, 430 includes fourrows of openings rather than seven rows of openings, as is the case withthe caddy 30. However, any effective number of rows or arrangement ofopenings are contemplated for various embodiments of the caddy.

Referring to FIG. 6, the caddy 130 includes a substantially planar topelement 131 with openings 40, 145, 146, 147 that are similar in shape,but are provided with different sizes. Opening 145, for example, issubstantially the shape of a skeleton key keyhole, with a substantiallyrectangular opening component 143 and an intersecting, adjacentsubstantially round opening component 148. The substantially roundopening components of the openings 146, 147 and 40 are progressivelysmaller, in that order. The overall length of the openings 145, 146, 147and 40 are progressively longer, in that order. Consequently, only oneparticular size of an available holder combined with medical implant maybe received within each of the openings in the caddy 130. For example, aholder 120 includes a cylindrical portion 128 that has a larger diameterthan any of the substantially round opening components of the openings146, 147, 40, and therefore the holder 120 would not fit inside any ofthe openings 146, 147, 40. Similarly, the combined width of the planarportion parallel with the side surface 23 and the cylindrical portion 28is longer than any of the openings 145, 146, and 147, and therefore theholder 20 would not fit inside any of the openings 145, 146, 147. Byapplication of these mechanisms, when the holders and medical implantsare received in the opening in which they will fit, the holders arepositioned at predetermined locations in the caddy 130.

The caddy 130 includes size labeling or indicia for rows of 12 mm, 16mm, 20 mm, and 24 mm long medical implants on the substantially planartop element 131. Correlating markings or indicia 24 are shown on the topsurface 21 of the holder 20 which is configured to couple with acorresponding medical implant 10. Similarly, a correlating marking orindicia 124 (i.e., the number “12”) is shown on the top surface 121 ofthe holder 120. The designator “12” in this example designates a medicalimplant that is 12 mm long, which in this embodiment corresponds to themedical implant 111. As describe herein, openings 40, 145, 146, and 147are of different sizes. In this embodiment, the different sizes of theopenings correlate with medical implants of different sizes.

Referring to FIG. 7, the caddy 230 includes a substantially planar topelement 231 with openings 40, 245, 246, 247 that are similar in size,but have different shapes. Opening 40, for example, is substantially theshape of a skeleton key keyhole, as described above. Opening 247includes a substantially rectangular opening component and anintersecting, adjacent substantially triangular opening component.Opening 246 includes a substantially rectangular opening component andan intersecting, adjacent substantially triangular opening componentoriented opposite from the triangular opening component of the opening247. Opening 245 includes a substantially rectangular opening componentand an intersecting, adjacent irregular polygonal opening component.Consequently, only one shape of an available holder combined with acorresponding medical implant may be received within each of theopenings in the caddy 230. For example, a holder 220 that includes anirregular polygonal portion 228 will not fit in any of the openings 246,247 and 40. Similarly the cylindrical portion 28 of the holder 20 wouldinterfere with one or more of each of the converging sides of theopenings 245, 246 and 247, and thereby prevent the holder 20 from beingreceived within any of the openings 245, 246 and 247. By application ofthese mechanisms, when the holders and medical implants are received inthe opening in which they will fit, the holders are positioned atpredetermined locations in the caddy 230.

The caddy 230 includes size labeling or indicia for rows of 12 mm, 16mm, 20 mm, and 24 mm long medical implants on the substantially planartop element 231. Correlating marking or indicia 24 are shown on the topsurface 21 of the holder 20 which is configured to couple with themedical implant 10. Similarly, correlating marking or indicia 224 (i.e.,the number “12”) is shown on the top surface 221 of the holder 220. Thedesignator “12” in this example is used to designate a medical implantthat is 12 mm long, which in this embodiment corresponds to the medicalimplant 111. As describe herein, openings 40, 145, 146 and 147 havedifferent shapes. In this embodiment, the different shapes of theopenings correlate with medical implants having different sizes.

Referring to FIG. 8, the caddy 330 includes a substantially planar topelement 331 with openings 40, 145, 146, 147 that are similar in shape,but are provided with different sizes. Opening 145, for example, issubstantially the shape of a skeleton key keyhole with a substantiallyrectangular opening component 143 and an intersecting, adjacentsubstantially round opening component 148. The substantially roundopening components of openings 146, 147 and 40 are progressivelysmaller, in that order. The overall length of the openings 145, 146, 147and 40 are progressively longer, in that order. Consequently, only onesize of an available holder combined with a corresponding medicalimplant may be received within each of the openings in the caddy 330.For example, a holder 320 includes a cylindrical portion 328 that has alarger diameter than any of the substantially round opening componentsof the openings 146, 147, 40, and therefore the holder 320 would not fitinside any of the openings 146, 147, 40. Similarly, the combined widthof the planar portion parallel with a side surface 1323 and acylindrical portion 1328 is longer than any of the openings 145, 146 and147, and therefore the holder 1320 would not fit inside any of theopenings 145, 146, 147. By application of these mechanisms, when theholders and medical implants are received in the opening in which theywill fit, the holders are positioned at predetermined locations in thecaddy 330.

The caddy 330 includes size and type labeling or indicia for rows of 12HA, 14 HA, 12F and 14F medical implants on the substantially planar topelement 331. In this example, the number corresponds to a lengthdesignation, and the HA and F indicate hydroxyapatite coating andfenestrated, respectively. Therefore, for example, 12HA is labeling fora 12 mm long hydroxyapatite coated medical implant. Correlating markingor indicia 324, “12HA”, is shown on the top surface 321 of the holder320, which is configured to couple with the medical implant 311.Similarly, correlating marking or indicia 1324, “14F”, is shown on thetop surface 1321 of the holder 1320, which is configured to couple withthe medical implant 310. As describe herein, openings 40, 145, 146 and147 have different sizes. In this embodiment, the different sizes of theopenings correlate with medical implants having different types anddifferent sizes.

Referring to FIG. 9, the caddy 430 includes a substantially planar topelement 431 with openings 40, 245, 246, 247 that are similar in size,but which have different shapes. Opening 40, for example, issubstantially the shape of a skeleton key keyhole, as described above.Opening 247 includes a substantially rectangular opening component andan intersecting, adjacent substantially triangular opening component.Opening 246 includes a substantially rectangular opening component andan intersecting, adjacent substantially triangular opening componentoriented opposite from the triangular opening component of the opening247. Opening 245 includes a substantially rectangular opening componentand an intersecting, adjacent irregular polygonal opening component.Consequently, only one shape of an available holder combined with acorresponding medical implant may be received within each of theopenings in the caddy 430. For example, a holder 420 that includes anirregular polygonal portion 428 will not fit in any of the openings 246,247 and 40. Similarly the cylindrical portion 1328 of the holder 1320would interfere with one or more of each of the converging sides of theopenings 245, 246 and 247 and thereby prevent the holder 1320 from beingreceived within any of the openings 245, 246 and 247. By application ofthese mechanisms, when the holders and medical implants are received inthe opening in which they will fit, the holders are positioned atpredetermined locations in the caddy 430.

The caddy 430 includes size and type labeling or indicia for rows of 12HA, 14 HA, 12F and 14F medical implants on the substantially planar topelement 431. In this example, the number corresponds to a lengthdesignation, and the HA and F indicate a hydroxyapatite coating andfenestrated, respectively. Therefore, for example, 12HA is labeling orindicia for a 12 mm long hydroxyapatite coated medical implant.Correlating marking or indicia 424, “12HA”, is shown on the top surface421 of the holder 420, which is configured to couple with acorresponding medical implant 311. Similarly, correlating marking orindicia 1324, “14F”, is shown on the top surface 1321 of the holder1320, which is configured to couple with a corresponding medical implant310. As describe herein, openings 40, 245, 246 and 247 have differentsizes. In this embodiment, the different types of the openings correlatewith medical implants having different types and different sizes.

Various embodiments of devices described herein wholly or their partsindividually may be made from any biocompatible material. The medicalimplant of some embodiments is capable of undergoing one or more steamsterilization cycles, or other sterilization procedures, withoutdegrading in a manner that would make the implant unsuitable for use ina medical or surgical procedure. For example and without limitation,biocompatible materials may include, in whole or in part: non-reinforcedpolymers, reinforced polymers, metals, ceramics and combinations ofthese materials. Reinforcing of polymers may be accomplished withcarbon, metal, or glass or any other effective material. Examples ofbiocompatible polymer materials include polyamide base resins,polyethylene, low density polyethylene, polymethylmethacrylate (PMMA),polyetheretherketone (PEEK), polyetherketoneketone (PEKK), a polymerichydroxyethylmethacrylate (PHEMA), and polyurethane, any of which may bereinforced. Example biocompatible metals include stainless steel andother steel alloys, cobalt chrome alloys, tantalum, titanium, titaniumalloys, titanium-nickel alloys such as Nitinol and other superelastic orshape-memory metal alloys. Components described herein may be formed byconventional milling or casting processes, by any type ofthree-dimensional printing or deposition based processes, or by anyother effective or suitable process.

One embodiment of the invention is directed to a method of providing amedical implant assembly that may include manufacturing a medicalimplant. For example, medical implants may include devices such asmedical implants 10, 111, 310 and 311 described herein. Methodembodiments may also include providing a holder for the medical implantthat has a first area and a second area, wherein the second area is atleast in part substantially perpendicular to the first area. Exemplaryholders described herein include holders 20, 120, 220, 320, 420 and1320, each having respective top surfaces and side surfaces that embodythe first area and the second area. Method embodiments may also includecoupling the holders to the medical implants, and providing a caddyconfigured to receive the holder coupled to the medical implant anddisplay the first area markings or indicia.

One embodiment of the invention is directed to a method of providing amedical implant assembly that may include manufacturing a medicalimplant and packaging the medical implant with a holder. Manufacturedmedical implants may include devices such as medical implants 10, 111,310 and 311 described herein. Exemplary holders are described herein andinclude holder 20, 120, 220, 320, 420 and 1320. The medical implants andholders of various embodiments may be packaged within any effective ofsuitable package or device that contains them. Exemplary packaging mayinclude materials that are resistant to the passing of toxins, bacteria,viruses, and other unwanted substances, but which permit one or more ofsterilization substances and sterilizing energy transmissions to passthrough to the medical implant and the holder. For example and withoutlimitation, such a sterilization substance may include ethylene oxide. Anon-limiting example of a sterilizing energy transmission is gammaradiation. In some embodiments, the packaging used may provide asubstantially hermitically sealed package.

Embodiments of the holder are marked with identifying information.Identifying information may include one or both of information about theimplant or type of implant generally, and/or specific information aboutthe manufacture and use of the implant. Exemplary types of identifyinginformation that may be employed include a device identifier and aproduction identifier, as defined by the U.S. Food and DrugAdministration as part of Unique Device Identification (“UDI”) guidanceand rules. A UDI is a unique numeric or alphanumeric code that consistsof two parts:

-   -   1.) a device identifier, a mandatory, fixed portion of a UDI        that identifies the labeler or manufacturer and the specific        version or model of a device; and    -   2.) a production identifier, a conditional, variable portion of        a UDI that identifies one or more of the following when        included:        -   the lot or batch number within which a device was            manufactured,        -   the serial number of a specific device,        -   the expiration date of a specific device,        -   the date a specific device was manufactured, and/or        -   the distinct identification code required by § 1271.290(c)            for a human cell, tissue, or cellular and tissue-based            product regulated as a device.

Another act of some method embodiments includes sterilizing the medicalimplant and the holder. Any effective sterilization method or substancemay be used in various embodiments. Sterilization may be accomplished atone or more of the following stages: prior to packaging, while packaged,and after removal from a package.

In one exemplary embodiment, sterilization may be accomplished while themedical implant and holder are packaged, the package may be opened, andthe medical implant and holder may be placed in a caddy. While in thecaddy, the medical implant and holder may be re-sterilized one or moretimes. For example, a replacement medical implant and holder may besupplied to a caddy as part of an array of medical implants and holders.The medical implant and holder may remain in the caddy until theparticular size or type of medical implant is required for a medical orsurgical procedure. Until the size or type of the medical implant isused, the medical implant may be re-sterilized with the caddy beforeeach procedure in which the caddy is present.
